Description

Technical Field

[0001] The invention relates to the technical field of postoperative rehabilitation equipment, in particular to a toilet used after knee joint surgery. Background Art

[0002] The toilet seat used after knee surgery is an auxiliary device designed for patients with limited mobility during postoperative rehabilitation. It provides convenience for patients with limited mobility after knee surgery, allowing them to use the toilet more easily and reduce the risk of patients falling during toileting, especially in cases of weak or unstable knee joints. When using a toilet after knee surgery, the patient can use a walker, a cane or with the help of a caregiver to slowly move to the toilet after knee surgery, and then sit down slowly and carefully. During the sitting process, the patient can use the armrests to provide additional support and stability. After the patient sits down, the patient can start to defecate. During the defecation process, the patient should maintain a correct sitting posture and avoid maintaining the same posture for a long time to reduce the pressure on the knee joint; During use, the existing toilet seats used after knee surgery are mostly of high height, which is difficult to meet the needs of different patients, causing patients to feel discomfort or pain when using them, prolonging recovery time. When sitting or standing, patients usually need greater knee flexion, which increases the pressure and pain of the knee joint, thereby affecting the patient's recovery process.
